TdxRangeControlDateTimeScale.RoundDate(TDateTime) Method

Rounds the specified date/time value to the beginning of the nearest whole time interval equal to the measurement unit used to graduate the scale.

Declaration

function RoundDate(const ADate: TDateTime): TDateTime; virtual;

Parameters

Name	Type
ADate	TDateTime

Returns

Type
TDateTime

Remarks

Normally, this function supports the internal infrastructure and is not intended to be used directly from your code. The RoundDate function is called internally by the GetNearestNormalizedAcceptableValue function provided by a Date/Time-based data range selection and visualization model.

If you are implementing a custom date/time scale, you may need to override the RoundDate function in a TdxRangeControlDateTimeScale descendant in order to allow the scale to work with custom measurement units.
